I had problems with my fob when pushing the buttons and nothing would happen. If I pushed really hard multiple times I could get it to work(sometimes). I kept thinking my batteries were bad, except that it is my wife's car and I don't use it that much. So I tried using a 2032 I have for my other car and it solved the problem. The 2032 are slightly thicker but same diameter. I think the slightly thicker battery may help it make contact better. Now they work great with the slightest touch of the buttons. Hope that helps. I have a 2010 GT AWD.
